EPDM rubber hose

 

1. Material and characteristics

Material: EPDM is a copolymer of ethylene, propylene and a small amount of non-conjugated dienes. It is a type of EPDM rubber and is represented by EPDM (Ethylene Propylene Diene Monomer).

Characteristics:

Weather resistance, heat resistance and ozone resistance: The main chain of EPDM is composed of chemically stable saturated hydrocarbons and only contains unsaturated double bonds in the side chains. Therefore, it has excellent weather resistance, heat resistance and ozone resistance, and can withstand the effects of ultraviolet rays, ozone and high temperatures for a long time.

Chemical resistance: It has good resistance to a variety of chemicals such as alcohols, acids, alkalis, oxidants, etc., but its performance may decrease under the action of certain solvents and long-term concentrated acids.

Water vapor resistance: Better than its heat resistance, suitable for applications that need to withstand steam.

Low density and high filling: Low density, can be filled with a large amount of oil and additives, thereby reducing costs, while not affecting its physical and mechanical properties.

2. Performance advantages

High temperature resistance: It can withstand temperatures up to 150°C and can still operate stably under continuous high temperature environments. It is particularly suitable for occasions that require high-temperature transmission media, such as automotive heating pipes, industrial cooling water pipes, etc.

Aging resistance: It exhibits extremely strong aging resistance under sunlight, air and high temperature conditions, and can maintain the stability and service life of the material for a long time.

Stable physical and chemical properties: In high temperature environments, EPDM rubber hoses can maintain the stability of their physical and chemical properties.

3. Application areas

Automotive industry: Widely used in automotive braking systems, cooling systems, air conditioning systems, fuel systems, etc., its high temperature resistance and acid and alkali resistance enable these hoses to work stably for a long time under high temperature and complex chemical environments.

Industrial manufacturing: Suitable for the transportation of a variety of chemical media, including water, steam, acid and alkali solutions, etc., and is often used in chemical plants, pharmaceutical plants, food industries and other fields to ensure safe and reliable material transportation during the production process.

Construction industry: It can be used for water supply and drainage systems of buildings. Its high temperature resistance enables the hose to maintain good use effect even in high temperature environment in summer, providing strong guarantee for the normal operation of buildings. At the same time, it is also widely used in industrial wastewater treatment, sewage treatment and discharge systems, and can withstand certain corrosive media and high temperature to ensure the stable operation of environmental protection facilities.

Agriculture: It is commonly used in farmland irrigation systems, agricultural spray systems, agricultural fertilizer transportation, etc. Its anti-aging and anti-ultraviolet properties enable the hose to be used for a long time in outdoor environments, providing strong support for agricultural production.

4. Production process

The production process of EPDM rubber hose mainly includes mixing, plasticizing, vulcanization and other links. During the mixing process, time and temperature need to be strictly controlled to ensure uniform mixing of the rubber. The temperature and time should be controlled in the plasticizing stage to ensure that the plasticization degree of the raw rubber is moderate. In the vulcanization stage, parameters such as temperature, pressure and time need to be strictly controlled to ensure that the performance of the rubber meets the expected requirements.

 

In summary, EPDM rubber hose has shown strong application potential in many industries with its excellent performance and wide application fields. With the continuous development of technology, its performance and application areas will be further expanded and improved.
